Fisher Whisper Trim lll Cage

Fisher Whisper Trim lll Cage

Fisher™ Whisper Trim lll cages provide effective attenuation of aerodynamic noise in vapor, gas, or steam applications involving high pressure drops or high pressure drop ratios. Using a Whisper Trim lll cage in conjunction with a properly-sized valve body can substantially reduce the noise level of the control application. Aerodynamic noise is generated by the turbulence created in the flow of vapor, gas, or steam as the fluid passes through a control valve.

Critical Service Noise Abatement
Flow Characteristics Linear
  • Use of a Whisper Trim III cage in a properly sized valve can result in a noise reduction up to 30 dBA compared to the same valve with standard trim. Such a reduction would be similar to the reduction in noise level noticed when moving away from the noise source 94m (308 feet).
  • Whisper Trim III cages provide excellent noise reduction and high flow capacity with the proven control and durability offered by standard Fisher valve trims. The result is optimum overall performance at a minimum investment.
  • Quick change trim allows fast and easy inspection of the cage without taking the valve body out of the pipeline. Whisper Trim III is interchangeable with standard control valve trim.
  • Hardened materials of construction are standard to provide exceptional wear resistance.
